In small bowl, combine softened cream cheese, enchilada sauce, green chiles, cumin, and chili powder. Spread in an even layer on the bottom of a glass pie pan or 9'x9' casserole dish.
Brown ground beef in a skillet over medium heat. Once no longer pink, add in taco seasoning and water. Allow to simmer until liquid is slightly reduced. Pour on top of cream cheese layer.
Sprinkle shredded cheese on top of ground beef mixture.
In small bowl, combine all guacamole ingredients, using a hand beater to remove all clumps. Layer guacamole on top of cheese.
Transfer sour cream into a small Ziploc bag. Snip off the corner of the bag and pipe a spider web on top of the guacamole.
Serve with corn chips.
